How to best isolate TT from vibration?

Hi all:

I'm currently using a Systemdek IIX table, which has a floating suspension system. I have it on a Atlantis Reference rack, but have replaced the top shelf with a 18" x 18" x 2" brick paver, and use (8) Vibrapod 4's under the table itself to prevent vibration. I still suffer from some skipping unless I walk ever so softly in my music room, most noticably at the beginning of an LP. I'm looking for input regarding what you fine members consider to be the best, but yet economical, methods of isolating this table and nixing this problem. Thanks,

Jim

Unfortunately, (continuous) very low frequency seismic vibration forces the entire house or apt. to move up and down. Thus, wall mounting is only partially effective for isolating in the vertical direction - a "de-coupling" device is required to "de-couple" the audio component from the seismic vibration.

Note: My company specializes in vibration isolation.

Traffic, subways and other sources of Low Freq. Vibration (that shake the house) are included in my definition of "seismic vibration." The proof that wall mounting is not totally effective is to employ an isolation device under the component mounted on the wall. Even when the house is out in the country, away from the usual sources of vibration that plague city folk.

All frequencies of structural vibration will affect audio performance - especially the extremely low frequencies. Earth's crust motion (which is continuous and has a vibration peak in the range 1-3 Hz). It is a mistake to think that very low frequency vibrations, even in this 1-3 Hz range, do not have audible consequences.
